To all whom it may concern:

Be it known that I, WiLLL-ur II. RYTHEK, a citizen of the United States, residing at Somonauk, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in the Construction of It otaries for Use in Connection witlflVindmills, of which the following is a specification.

Heretofore it has been impossible to success fully use a ratchet-wheel with pawls or dogs to operate the same in connection with windmillrotaries, for the reason that the rapid and extended movement required in the pawl, to gether with the great pressure required to hold the pawl, in its downward movement, against; the ratchet-wheel, so as to insure the catching of the same into the teeth of the ratehetwvheel in its upward movmnent, would rapidly wear the teeth on the face of the wheel smooth, and of such shape that the pawls or dogs would soon slip over the surface of said ratchet-wheel without causing the same to rotate. M y invention affords a simple, cheap, durable, and

safe method by which the reciproeatory motion of the pitmau-rod of a windmill and the intermittent rotary motion of a ratchet-whecl used in connection therewith and actuated thereby in such a manner as to allow of a short and slow vibratory movement in the arm carrying the pawl is converted into a constant 1o tary motion of the shaft on which said ratchetwheel rotates and the machinery connected therewith; also, to providcnn-ans whereby the stopping of the machinery connected with said shaft by overwork or by the accidental clogging ofthe machinery may not break, injure, or interfere with the constant and regularmotion of the wind-wheel and pitman-rod; also, to reduce to a r'inimum the wear of the pawl or dog; actuating the ratchet wheel and the teeth of said ratcl et, as well. as to render the working of said pawl and ratchet safe. durable, certain, andnoiselcss.

[have illustrated my invention by the accom panyiug drawings, making a part of this specification, in which Figure l is a plan view of the windmill-rotary of my improved coir struction, and showing a method of attaching the pitinanrod to the arm or pawl. I prefer to attach it to the pawl communicating motion to the ratchet-wheel. Fig. 2 is a cross-section of the same on line 2 2 of Fig. Fig. 3 is a section of the bearing in which the main shaft of my rotary revolves, and around or upon which the arms or arm :arrying the pawl also rotates. Fig. 4 isa perspective View, showing the manner in whichl may attachthe pitmanrod of the windmill tothe arm carrying thepaivl or dog. Fig. 5 is a pers 'ieetive view of the manner in which I attach the pitmanrod of the windmill to the pawl or dog intihe place of attaching said pitman-rodto the arm carrying the pawl, as shown in Fig. 4. This is the method of mnstruction which I prefer. Fig. (5 is a perspective view of the armsor levers shown in Fig. 2 with springs attached,by which 1 convert the intermittent rotary motion ofthe ratchet-wheel into a constant rotary motion of the shaft on which said ratehet'whecl rotates.

Likelettei-s refer to likeparts throughout the severalviews.

C is the pawl or dog giving motion to ratchet-wheel l-;. is the point of said pawl in connection wilh teeth 1;. l isthe arin carrying the said pawl 1 1C are the hearings in which said shaft .1\. turns. 0 isthe cmitinuation of said bearings l) l around whicharm B partially rotates. l 1 are rods attached to or a continuation of the pitman-rod. /'is a plate to which said rods F 1 are attached. (l is the spring resting on said platcf, and compressed by the raising of said latc /'whcn arm'l) is not raised. 1/ is theplateagainst which the uppcrend of spring; (i pres. or by which it is held. 11 is a rod running through the center of spring G, and connected at point 11 with pawl and at the othci end with plate 1 l is an arm or lcvcr attached firmly to shaft A. K K K K. are arms or levers revolving loosely upon shaft .A.

h L L" L arc/springs separating said levers Pitman-rod F F is alternately raised and dcpressed by the action of the crank of the windshaft of the windmill. As the said rod dcpressed point e of pawl O is raised or loosened from contact with teeth I), (when constructed as shown in Fig. 2.) Further depression of the pitman-rod causes arm B to rotate partially around on bearing e. I prefer that the are described by said arm D shall measure about thirty degrees. The raising of the pitmair rod F F may compress spring G- suffieientlyto allow the windwheel to complete the revolution without causing any upward motion in arm I). This occurs when the machinery connected wit-h my rotary is overworked or accidentally clogged and it is only at such times that said spring G is called upon to perform its functions. At other times the raising of pitman-rod causes pawl C to be raised in unisontherewith, carrying with it arm 1 cansing said arm to partiallyrotate round bearings c e. .l't 'is obvious that before any upward movement can be communicated to pawl (l by pitman-rod F F when the same is attached to pawl C, as shown in. Fig. 2, the said pawl is first firmly pressed. against or into 'teeth b on ratchet-wheel l3, and that, as at this precisemoment the crankshaft of the wind-wheel, which I have before called the wind-shaft, is passing over its center, the movements of the pitmanrod F 1 and pointe of pawl (J are very slow and easy, and no injury can be done to said pawl or to ratchetieeth I). The upward move ment of pawl (I, as described, causes ratchetwheel B to partially rotate (through an arc of about thirty degrees) upou shaft A. At the same time arm or lever K is forced forward through the same are by means of stop M, shaft A remaining at rest, springs L L L L are compressed, lever .K K K K, each describing a less are than the preceding lever, and lever 1, remaining at rest with shaft A. \Vhen the forward motion of wheel 1 and lever K ceases they are held stationary by clutch M. Arm D and pawl (1' may be carried downward repeating their former motion by the action of the pitman-rod F F. Springs L ll L 1/ regain their normal condition gradually, causing levers K ii it .K to revolve. around shaft A, and lover l to revolve, carrying with it said. shaft. A. l.he action of these springs is such that a continuous rotary motion ,given'to said shaftA by means oflever I, said spri ngs not having exhausted their force until they shall have received a fresh impetus or eompre ion; by the action of ratchet-wln cl l; tln'ough stop M, actuated by pawl lf the form of construction of the arm I), pawl (l, and pitman-rod F F, with connectingspring G, platcs l' and rod l-[ (shown in Fig. 4) is used, it will. be necessary to attach a weight or spring to pawl to hold point 0 of said pawl againstteeth I) of ratchct-whwl B.

The windmill rotary invented and constructed by me and here described possesses many advantages over any rotary heretofore made. 'lhceost ofznyrotary is iniu-hlesstlnl'n any other, it is more durable and acts with greater certainty, and the work which the wind-wheel has to perform can under no circumstances exceed a given number of pounds, which is regulated by the size and strength of spring G. This spring is ofthe same strength, requiring the same number of pounds to compress it, as the springs L L L L, and hence the difference in leverage, resulting from the difference in length of the levers K, K, K, li, and l', and the length of the arm I), is the onlyexcess of power required in case of the stopping of the machinery .of the rotary, from overwork or accidental clogging, as hereinbefore described, with arm 1) remaining at rest.

It is obvious that arm D may be pivoted at or about point a on frame X X without in the least departing from my invention.

The arrangement or method of attaching the pitnian-rod to the pawl shown in Fig. 13in, sures a firm pressure of the pawl against the ratchetwheel. So' great is this pressure and so firm its hold that even a friction-clutch, without the invervention ofrat(.-het-tecth on the wheel. would operate the same, and such friction-clutch or smooth wheel in place of theteeth here shown would in no wise departfrom or be other than my invention. In case arms D l) are weighted, so that said arms shall remain stationary when turned at any point on bearings c c, the initial downward movement of the pitman-rod will actually raise point'c of pawl C from the face of the ratchet-whee]. If the arm is not weighted, however, point a will be pressed slightly against'the face ofthe ratchetovhcel by the tendency of arms I) D to assume a perpendicular position on bearings e e. The main objects of my invention are, however, obtained by the arrangement of the levers I K, &c., and springs L L, &c., placed, with ratchet-wheel B, on shaft A, as hereinbeforedescribed. By the use ofthcse springs and levers 1. am enabled to convert the inter" mittent rotary motion of the wheel B into a continuous motion of the shaft A, and amfurther enabled, in acertain degree, to equalize the variable movements-of the wind-wheel by the partial storage of power in said spring,- and produce, to a greater extent than has been heretofore attained, a constant and regular motion in the-machinery connected withthe rotary.

Havingthus described my invention and the manner of its construction and operation, what I claim, and desire to secure by Letters Patent, is
